I'm sorry but I need a little bit more context
Answer:
Flase
Explanation:
The cell cycle has two major phases: interphase and the mitotic phase. During interphase, the cell grows and DNA is replicated. Usually the cell will divide after mitosis in a process called cytokinetic in which the cytoplasm is divided and two daughter cells are formed.
hope this helps
have a great day/night :)
B. Experiment 1, because it gave the same results every time
Muscle cells require more energy than most other cells in order to function. Therefore, muscle cells would be expected to have more ________ and ________ than most other animal cells.
A) Glycogen; Mitochondria B) Peroxisomes; Fat C) Mitochondria; Starch D) Ribosomes; Glycogen E) Glucose; Nuclei.
Answer:
A) Glycogen; Mitochondria
Explanation:
Glycogen is the stored form of glucose present in the animal cells. In human beings, glycogen is mainly present in muscle cells and liver cells. Breakdown of glycogen releases glucose which in turn can be fueled into cellular respiration to produce the energy required for the muscle contraction.
The aerobic phases of cellular respiration are Kreb's cycle and electron transport chain. Both of these occur in the mitochondria. Therefore, muscle cells are rich in glycogen storage and have plenty of mitochondria to ensure the supply of ATP required for their contraction. The contraction of muscles requires lots of ATP molecules as a source of energy.
But it was not until 1928 that penicillin, the first true antibiotic, was discovered by Alexander Fleming, Professor of Bacteriology at St. Mary's Hospital in London.
